Spotted Spurge (Euphorbia maculata) is a fast-growing, resilient weed that can quickly take over lawns, gardens, and other landscapes. It is known for its distinctive appearance, with red or purple-spotted leaves and a mat-forming growth habit.

Controlling spotted spurge can be challenging due to its rapid growth and ability to spread quickly. In this article, we’ll explore the best herbicides available for effectively eliminating spotted spurge and offer tips for successful control.

10 Best Herbicides for Spotted Spurge

1. Roundup (Glyphosate)

Roundup (Glyphosate) is one of the most popular non-selective herbicides and is highly effective for controlling spotted spurge. It works by inhibiting an enzyme essential for plant growth, causing the plant to wilt and die within days.

Roundup is most effective when applied to actively growing spotted spurge. However, since it is non-selective, it can damage other plants in the area, so care must be taken during application.

For best results, apply Roundup when the spurge is young and actively growing. Use a targeted application method to minimize the risk to surrounding vegetation.

2. Preen Weed Preventer

Preen Weed Preventer is a pre-emergent herbicide that helps to control spotted spurge before it germinates. It works by preventing weed seeds from sprouting, providing long-term control of spurge and other annual weeds.

Preen is ideal for use in flower beds, vegetable gardens, and lawns. It’s best applied early in the growing season, before spotted spurge seeds begin to germinate.

This herbicide is gentle on established plants, making it a good choice for gardens and landscaped areas. However, it should not be used on newly seeded lawns or plants, as it may prevent desirable seeds from sprouting.

3. Image Herbicide

Image Herbicide is a selective herbicide that targets broadleaf weeds, including spotted spurge. It contains the active ingredient imazaquin, which disrupts the plant’s growth and prevents it from thriving.

Image works best when applied during the early stages of spurge growth. It’s a good choice for controlling spurge in lawns without harming grass.

This product is safe for many types of turfgrass, but it should not be used on some varieties, so it is important to read the label before use.

4. Trimec Classic

Trimec Classic is a selective post-emergent herbicide designed to control broadleaf weeds like spotted spurge. It combines three active ingredients to target and kill unwanted plants.

Trimec Classic is ideal for use in lawns and turf areas. It’s most effective when applied in the early stages of spurge growth and works by disrupting the plant’s metabolic processes.

It is safe for most cool-season grasses, but care should be taken to avoid application on warm-season grass varieties.

5. Ortho Weed B Gon

Ortho Weed B Gon is a selective herbicide that is effective against broadleaf weeds like spotted spurge. It contains the active ingredient 2,4-D, which disrupts the plant’s growth and causes it to die.

Ortho Weed B Gon is designed for use on lawns and is safe for many types of grass. It’s most effective when applied to actively growing spotted spurge during the growing season.

This herbicide is easy to apply and offers fast results, making it a good choice for homeowners seeking effective weed control in their lawns.

6. SedgeHammer Herbicide

SedgeHammer is an effective herbicide that targets both sedges and broadleaf weeds like spotted spurge. It contains halosulfuron-methyl, which inhibits the growth of target plants.

SedgeHammer is ideal for use in lawns, golf courses, and landscape areas where spotted spurge is a problem. It works by inhibiting the plant’s ability to produce chlorophyll, causing it to die off.

This herbicide is highly effective on sedges and is relatively safe for most types of turfgrass. However, it should not be used on certain plant types, so be sure to read the label before applying.

7. Spectracide Weed Stop

Spectracide Weed Stop is a powerful herbicide that controls a wide range of weeds, including spotted spurge. It works by targeting broadleaf plants and stopping their growth.

This herbicide is ideal for use in lawns and flower beds. It provides fast results and is best applied to actively growing spurge plants.

Be cautious when using Spectracide, as it can harm desirable plants if not applied carefully. Always follow the label instructions for safe and effective use.

8. Amitrole Herbicide

Amitrole is a non-selective herbicide that can be used to control spotted spurge. It works by inhibiting plant growth and can be applied to both pre-emergent and post-emergent stages.

Amitrole is most effective when applied directly to the foliage of spotted spurge. It’s a good option for spot treatments in areas where targeted control is needed.

Care should be taken to avoid contact with desirable plants, as Amitrole is non-selective and can damage other vegetation.

9. Natria Lawn Weed Control

Natria Lawn Weed Control is a natural herbicide that effectively controls spotted spurge without synthetic chemicals. It contains corn gluten meal, a natural weed preventer that inhibits seed germination.

This herbicide is perfect for those seeking a more environmentally friendly option for controlling spurge. It is safe for lawns and can be used on a variety of grass types.

While it is effective for pre-emergent control, Natria may not be as effective on established spotted spurge, making it better suited for early-season applications.

10. VPG Fertilome Broadleaf Weed Killer

Fertilome Broadleaf Weed Killer is a selective herbicide that targets a wide range of broadleaf weeds, including spotted spurge. It contains dicamba and 2,4-D to disrupt the growth of the targeted plants.

Fertilome works well on both active growth and pre-emergent spurge. It is safe for many types of grass and can be used in lawns and landscaped areas.

For the best results, apply Fertilome in the spring or fall, when spotted spurge is actively growing.

Buyer’s Guide for Herbicides

Choosing the right herbicide for spotted spurge control depends on several factors, such as the size of the infestation, the time of year, and the type of area you are treating. Below are some important considerations to guide your purchase:

• Type of Herbicide: Decide between pre-emergent or post-emergent herbicides. Pre-emergents are best for preventing the spread of spurge, while post-emergents are effective for treating existing infestations.
• Targeted vs. Non-Selective: Non-selective herbicides kill all plants they come into contact with, so use them carefully. Selective herbicides target specific plants and are a better choice for lawns.
• Application Method: Herbicides come in liquid and granular forms. Liquid forms can be more effective for large areas, while granular products are easier for smaller, controlled applications.
• Environmental Impact: If you are concerned about environmental effects, look for natural or organic herbicides like Natria that are safer for beneficial insects and pets.
• Speed of Action: Some herbicides provide fast results, while others take time to show effectiveness. If you need quick results, consider products like Roundup.

Conclusion

Controlling spotted spurge requires a thoughtful approach, as different herbicides work best at different stages of the plant’s growth. Whether you choose a pre-emergent or post-emergent herbicide, selecting the right product is key to successfully managing this persistent weed.

Remember to apply herbicides at the right time and use them according to the label instructions to avoid harming desirable plants. With the right products and proper care, you can keep your landscape free of spotted spurge and other troublesome weeds.

Choose the herbicide that best suits your needs and enjoy a healthier, weed-free garden or lawn!
